No phosphateBy Michael on 7/29/2015

Had a problem starting with bubble algae and one problem area with turf algae. Ordered and used this in a BRS reactor SUPRISE no more algae and no phosphate. Works great, just use less than recommended at first so you don't shock your system. Takes about 3 gallons of RO to flush fines and rust color from the water. Ordered more when I ran out and will continue to use it.

Saw significantly less hair algae after about 2 weeks. Works for me.

Best GFOBy Shawnon 7/4/2015

One of the best ways to drop those nasty phoshate levels in a hurry. I honestly never tried another brand but I don't intend to if BRS keeps making quality GFO.

Very important piece of the algae free puzzle.

Slightly larger pellets are awesome. By Turfon 6/7/2015

Turf would recommend this product to a friend

The slightly larger pellet size has made it substantially easier to deal with in a filter sock or reactor the ones I've used in the past.

Brs Gfo is affective and very easy to use. Just follow the instructions on the container or hit up BRS online and the calculator with help you out.

Worth itBy Soseeon 5/21/2015

Sosee would recommend this product to a friend

a good value but don't use the amounts they recommend in the reactor. I followed the advice of a seasoned reefer and used half the recommended amount and it works great! Using too much can effect your alk levels.

I'm assuming by my lack of green dlime and hair algae it has worked as promised. Thanks
